Does access through the pronator quadratus influence pronation strength in palmar plate fixation of distal radius fractures in elderly patients?
Palmar plate fixation of the distal radius fracture involves dissecting the pronator quadratus (PQ). This is regardless of whether the approach is radial or ulnar to the flexor carpi radialis (FCR) tendon. It is not yet clear whether and to what extent this dissection leads to a functional loss of pronation or pronation strength. The aim of this study was to investigate the functional recovery of pronation and pronation strength after dissection of the PQ without suturing. ⋯ The present study can show a recovery of pronation as well as pronation strength in a large patient population. At the same time, the pronation strength is still significantly lower 1 year after the operation than on the opposing healthy side. As the pronation strength recovers as the grip strength and is at all times on a par with the supination strength, we believe that we can continue to refrain from re-fixating the pronator quadratus.

Obese elderly patients with hip fractures may have better survival outcomes after surgery.
In recent years, there has been an increasing amount of research on the "obesity paradox". So our primary objective was to explore whether this phenomenon exists in our study, and secondary objective was to determine the effect of body mass index (BMI) on major complications, and the incidence of acute kidney injury (AKI) after hip fracture surgery after controlling for confounding factors. ⋯ The 1-year mortality risk of patients with higher BMI was significantly reduced. Besides, compared with normal-weight patients, underweight patients and obese patients have a higher risk of major complications; low-weight and obese patients are at higher risk for AKI.

Osteoid osteoma in the bones of the hand: a systematic literature review.
Osteoid osteoma (OO) is a common benign bone tumor. OO is observed most frequently in the long bones, especially in the tibia and femur. When occurring in the bones of the hand, OO can be a diagnostic and therapeutic challenge. The aim of this study was to provide a systematic review of occurrence, symptoms, diagnosis and treatment options regarding OO in hand bones. ⋯ Osteoid osteomas in the bones of the hand are rare and a delayed diagnosis is common. In cases of pain combined with particular symptoms such as nail hypertrophy and swelling OO should be considered. Of the most used imaging methods, CT scans have the highest sensitivity.

Is lesser tuberosity morphology related to subscapularis tears and anterior shoulder instability?
Although the morphological relationship of the scapula and the humeral head has been claimed to be related to shoulder pathologies, few studies examined the relationship between subscapularis (Ssc) tears and lesser tuberosity (LT)-humeral head (HH) and between Ssc tears and HH-glenoid. This study aims to evaluate the relationship of LT with HH and glenoid in patients with Ssc tears and anterior shoulder instability (ASI). We hypothesized that the glenoid, HH, and their combined relationship with LT may impact Ssc tears and ASI. ⋯ III retrospective comparative study.

Complications following arthroscopic-assisted coracoclavicular stabilization in patients with unstable lateral clavicle fractures.
Lateral clavicle fractures are unstable and prone to nonunions, which is why they are often treated surgically rather than conservatively. Despite the variety of surgical techniques found in the literature, the best method for treating this rare fracture type has not yet been determined. Our case series aimed to describe a coracoclavicular (CC) reconstruction technique and to assess complications and patient outcomes 1 year postoperatively. ⋯ Restoring the CC ligaments alone could not reliably achieve fracture stability, with more than one-third of cases in this series experiencing major complications. Given the high revision and nonunion rates, we do not recommend this type of surgical technique.
